middlebrow
1911年（形容词）“具有平均或适度的文化兴趣； ”1912年（名词）“具有平均或适度文化兴趣的人”，来自 middle（形容词）+ brow（比较 highbrow， lowbrow）。
[T]here is an alarmingly wide chasm, I might almost say a vacuum, between the high-brow, who considers reading either as a trade or as a form of intellectual wrestling, and the low-brow, who is merely seeking for gross thrills. It is to be hoped that culture will soon be democratized through some less conventional system of education, giving rise to a new type that might be called the middle-brow, who will consider books as a source of intellectual enjoyment. ["The Nation," Jan, 25, 1912]
“高眉毛”认为阅读是一种贸易或智力搏斗形式，而“低眉毛”仅寻求粗俗的刺激，两者之间存在着惊人的巨大鸿沟，我几乎可以说是真空。希望通过一些非传统的教育体系，文化很快就会实现民主化，产生一种新型人才，可以称之为“中眉毛”，他们将把书籍视为一种智力享受的来源。【《国家》杂志，1912年1月25日】
